Subwoofer stopped working

I have had a set of 2.1 Klipsch speakers for around 8 years, but now my subwoofer does not want to work. Sometimes I can jiggle the plug into place so that it does, but then other times it just won't work. It's like the metal in the plugs aren't touching. Is there a way to fix this, or should I be looking in to new speakers?

since I've never laid hands on a soldering iron before I'd probably look to someone else to do it. Do you know if it's an expensive thing to get fixed?

15 minutes, if what you mentioned is the only issue on that system but they may charge you an hour minimum but should not be more. The cost is from 20 to 60 Dollars depending on your location; if you live in a third world country the labour would be a lot less.

If you think you're comfortable enough then this could be a learning experience for you, so I would say do it yourself, of course you'll get the satisfaction of being fix it yourself and if you could not do it then have someone else fix the problems. The soldering iron would cost $5.00 and up plus the soldering lead which is about $3.00 for a small piece.
